摘　　要： 目的报告一种新的基因芯片荧光标记技术:通用引物U2联合标记技术(universal primer U2 labeling ,UPL);比较UPL与随机引物等其他标记方法的效率和可重复性。方法流感病毒RNA用四种标记方法处理后与流感病毒寡核苷酸检测芯片杂交,用Spss10.0对杂交结果进行分析。结果UPL方法在标记物杂交的荧光强度、信噪比、探针真阳性率和可重复性等方面均高于随机引物逆转录掺入标记法,而与其他两种RD标记方法相当,但标记过程相对更加简单。结论UPL方法可用于基因芯片研究和应用。 Objective To develop a new method for fluorescent labeling technique, universal primer U2 labeling (UPL), for microarray studies. Method Influenza virus RNA was labeled with four labeling methods, namely UPL, random primer, restriction display incorporation labeling method and reverse transcription coupled random primer spiking labeling method (RT-PSL), respectively, and hybridized to influenza virus oligonucleotide microarray. The signals extracted from the microarrays were analyzed with SPSS 10.0 software to compare the efficiency and reproducibility of the labeling methods. Results The fluorescence intensity, signal-to-noise ratio (SNR), true positive ratio (TPR) of the probes and reproducibility of labeling with UPL were comparable with those RD-labeling method, and higher than those of RT-PSL method. UPL reduced the complexity of the procedures in comparison with the other labeling methods. Conclusion UPL labeling method can be used in research and development of the microarray technique.
